An alternate, though undoubtedly more cumbersome way to do this might be to
use vectors of a sort:
vector *v;
v_create(&v, 3 /*initial*/, 0 /*maxgrow*/);
v_append(v, vdesc_ipfw_proto, myproto);
v_append(v, vdesc_ipfw_ip, myfromip);
v_append(v, vdesc_ipfw_ip, mytoip);
say("Deny \1 from \2 to \3", v);
v_destroy(v);
This mechanism might, however, be reused later, somewhat similar to the va
functions, except that we attach arbitrary descriptors to the data that can
be used for various forms of rendring and special handling.
I have used things like this in my code before, and could supply the code
used there if it is desireable.
